public class JRadioButtonMenuItem
extends JMenuItem
implements Accessible
An implementation of a RadioButtonMenuItem. A RadioButtonMenuItem is a menu item that is part of a group of menu items in which only one item in the group can be selected. The selected item displays its selected state. Selecting it causes any other selected item to switch to the unselected state. Used with a ButtonGroup object to create a group of menu items in which only one item at a time can be selected. (Create a ButtonGroup object and use its add method to include the JRadioButtonMenuItem objects in the group.)

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JRadioButtonMenuItem key assignments.

Warning: serialized objects of this class will not be compatible with future swing releases. The current serialization support is appropriate for short term storage or RMI between Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
